ABSTRACT

Disclosed are a method, a device and/or a system of utilizing a camera array system to detect a load status of a semi-trailer truck. A sensor array is affixed to a surface of a trailer of the semi-trailer truck to automatically determine whether a cargo area of the semi-trailer truck is occupied. A set of cameras of the sensor array have each camera embedded in individual recesses of the sensor array. The cargo area is illuminated using at least one light source of the sensor array. A memory and a processor associated with the sensor array are configured to store one baseline image of the cargo area of the trailer in an empty state. The processor is configured to detect a triggering event. The processor determines a cargo status based upon a difference between the current image and the baseline image, and sends the cargo status to a dispatcher.

FIELD OF TECHNOLOGY

This disclosure relates generally to automotive technology and, more particularly, to a method, a device and/or a system of utilizing a camera array system to detect a load status of a semi-trailer truck.

BACKGROUND

A transportation service provider (e.g., a logistics provider) may be compensated based on a type of goods being carried inside a cargo area of a trailer of a transportation vehicle (e.g., a semi-trailer truck). Therefore, the transportation service provider may seek to maximize a utilization of space inside of a cargo area of the trailer. Sensors (e.g. weight sensors, wave sensors, ultrasound sensors) employed in an interior space of the cargo area may not be able detect color patterns or types of cargo.

Further, these sensors may not be able to detect exactly where in the trailer the cargo is located. Moreover, these sensors may not provide a reliable view of what is exactly happening inside of the trailer. As a result, new problems may arise such as a driver may embark on long journeys, when, in fact, their cargo area is filled with the wrong type of cargo (e.g., may even be empty). This may lead to wasted time, fuel, efficiency, customer dissatisfaction, and/or ultimately, loss of revenue for the transportation services provider.

SUMMARY

Disclosed are a method, a device and/or a system of utilizing a camera array system to detect a load status of a semi-trailer truck.

In one aspect, a trailer of a semi-trailer truck includes a sensor array affixed to a surface of the trailer to automatically determine whether a cargo area of the semi-trailer truck is occupied. The trailer of the semi-trailer truck includes a set of cameras of the sensor array. Each camera of the set of cameras is each embedded in individual recesses of the sensor array such that each of the set of cameras does not protrude from the sensor array into the cargo area and/or each of the set of cameras peers into the cargo area of the semi-trailer truck. The trailer of the semi-trailer truck further includes at least one light source to illuminate the cargo area. A memory and a processor associated with the sensor array are configured to store one baseline image of the cargo area of the trailer when the trailer is in an empty state. The processor is configured to detect a triggering event and to illuminate the cargo area of the trailer using at least one light source. The processor is further configured to capture a current image of the cargo area of the trailer using the set of cameras. The processor is configured to compare each current image of an interior cavity with the corresponding baseline image of a cargo cavity. The processor determines a cargo status based upon a difference between the current image and the baseline image. The processor is also configured to send the cargo status to a dispatcher using a cellular modem.

The sensor array may be affixed to an upper corner of the trailer. The sensor array may be affixed to a middle top-section of the trailer, such that the sensor array is placed in a separate housing from the cargo area on an exterior face of the trailer. The light source may be a light-emitting diode that is associated with each camera of the set of cameras. Each camera of the set of cameras may automatically take a photograph of the cargo area in view of each camera upon an occurrence of the triggering event. The triggering event may be a trailer opening event, a trailer closing event, a motion detection event through a global positioning device and a motion sensor in the trailer, a stopping event, a time-based event, a geographic-location based event, and/or a velocity based event.

The sensor array may include a backup camera to observe a rear area of the trailer of the semi-trailer truck. The backup camera may be mounted to the sensor array. The backup camera may view a door of the trailer, a loading area of the trailer, and/or an area behind the trailer. A driver of the trailer may view a video feed from the backup camera using a wired connection and/or a wireless connection between the backup camera and a display in a cabin area of the semi-trailer truck. The trailer of the semi-trailer truck may have a field of view of each of the set of cameras to partially overlap with the field of view of another of the set of cameras. The sensor array may be powered by a battery, the semi-trailer truck, and/or a solar array mounted on the trailer.

The sensor array may communicatively generate a composite view of the cargo area using the set of cameras. The sensor array may communicate the composite view to the cabin area of the semi-trailer truck and/or a central server communicatively coupled with the semi-trailer truck through an Internet network using the processor and the memory of the semi-trailer truck. The cellular modem may periodically provide a reporting of a location of the semi-trailer truck captured with a geographic positioning receiver to the central server along with the composite view using the processor and the memory.

In another aspect, a trailer of a semi-trailer truck includes a sensor array affixed to a surface of the trailer to automatically determine whether a cargo area of the semi-trailer truck is occupied. The trailer of the semi-trailer truck further includes a set of cameras of the sensor array. Each camera of the set of cameras is each recessed relative to an interior region of the cargo area and/or each of the set of cameras peers into the cargo area of the semi-trailer truck. A memory and a processor associated with the sensor array are configured to store one baseline image of the cargo area of the trailer when the trailer is in an empty state. The processor is configured to detect a triggering event and to illuminate the cargo area of the trailer using at least one light source. The processor is further configured to capture a current image of the cargo area of the trailer using the set of cameras. The processor compares each current image of an interior cavity with the corresponding baseline image of a cargo cavity. The processor of the sensor array is configured to determine a cargo status based upon a difference between the current image and the baseline image. Furthermore, the processor is configured to send the cargo status to a dispatcher using a cellular modem.

In yet another aspect, a trailer of a semi-trailer truck includes a sensor array affixed to a surface of the trailer to automatically determine whether a cargo area of the semi-trailer truck is occupied. The trailer of the semi-trailer truck also includes a set of cameras of the sensor array. Each camera of the set of cameras is each embedded in individual recesses of the sensor array such that each of the set of cameras are interior to a flush plane of the surface to prevent cargo from damaging each camera. Each of the set of cameras peers into the cargo area of the semi-trailer truck. The trailer of the semi-trailer truck further includes at least one light source to illuminate the cargo area. A memory and a processor associated with the sensor array are configured to store one baseline image of the cargo area of the trailer when the trailer is in an empty state. The processor is configured to detect a triggering event and/or to illuminate the cargo area of the trailer using at least one light source.

DETAILED DESCRIPTION

Disclosed are a method, a device and/or a system of utilizing a camera array system to detect a load status of a semi-trailer truck.

In one embodiment, a trailer 102 of a semi-trailer truck 104 includes a sensor array 106 affixed to a surface 108 of the trailer 102 to automatically determine whether a cargo area 110 of the semi-trailer truck 104 is occupied. The trailer 102 of the semi-trailer truck 104 also includes a set of cameras 112 of the sensor array 106. Each camera of the set of cameras 112 is each embedded in individual recess(es) 113 of the sensor array 106 such that each of the set of cameras 112 does not protrude from the sensor array 106 into the cargo area 110 and/or each of the set of cameras 112 peers into the cargo area 110 of the semi-trailer truck 104. The trailer 102 of the semi-trailer truck 104 further includes at least one light source 114 to illuminate the cargo area 110. A memory 116 and a processor 118 associated with the sensor array 106 are configured to store one baseline image 122 of the cargo area 110 of the trailer 102 when the trailer 102 is in an empty state.

The processor 118 is configured to detect a triggering event 206 (e.g., using the triggering event algorithm 142 of the dispatch server 126) and to illuminate the cargo area 110 of the trailer 102 using at least one light source 114. The processor 118 is further configured to capture a current image 144 of the cargo area 110 of the trailer 102 using the set of cameras 112. The processor 118 is configured to compare (e.g., using the difference algorithm 148 of the dispatch server 126) each current image 144 of an interior cavity 402 with the corresponding baseline image 122 of a cargo cavity. The processor 118 determines a cargo status 124 (e.g., using the cargo status algorithm 125 of the dispatch server 126) based upon a difference (e.g., using the difference algorithm 148 of the dispatch server 126) between the current image 144 and the baseline image 122. The processor 118 is also configured to send the cargo status 124 to a dispatcher 134 using a cellular modem 136.

The sensor array 106 may be affixed to an upper corner of the trailer 102. The sensor array 106 may be affixed to a middle top-section of the trailer 102, such that the sensor array 106 is placed in a separate housing 138 from the cargo area 110 on an exterior face 140 of the trailer 102. The light source 114 may be a light-emitting diode that is associated with each camera of the set of cameras 112. Each camera of the set of cameras 112 may automatically take a photograph of the cargo area 110 in view of each camera upon an occurrence of the triggering event 206. The triggering event 206 may be a trailer opening event, a trailer closing event, a motion detection event through a global positioning device and a motion sensor in the trailer, a stopping event, a time-based event, a geographic-location based event, and/or a velocity based event.

The sensor array 106 may include a backup camera 202 to observe a rear area 204 of the trailer 102 of the semi-trailer truck 104. The backup camera 202 may be mounted to the sensor array 106. The backup camera 202 may view a door of the trailer, a loading area of the trailer, and/or an area behind the trailer. A driver 208 of the trailer 102 may view a video feed 210 from the backup camera 202 using a wired connection and/or a wireless connection between the backup camera 202 and a display 212 in a cabin area 214 of the semi-trailer truck 104. The trailer 102 of the semi-trailer truck 104 may have a field of view 404 of each of the set of cameras 112 to partially overlap with the field of view 404 of another of the set of cameras 112. The sensor array 106 may be powered by a battery, the semi-trailer truck 104, and/or a solar array mounted on the trailer 102.

The sensor array 106 may communicatively generate a composite view 146 of the cargo area 110 using the set of cameras 112. The sensor array 106 may communicate the composite view 146 to the cabin area 214 of the semi-trailer truck 104 and/or a central server communicatively coupled with the semi-trailer truck 104 through an Internet network using the processor 118 and the memory 116 of the semi-trailer truck 104.

The processor 118 is further configured to capture a current image 144 of the cargo area 110 of the trailer 102 using the set of cameras 112. The processor 118 compares (e.g., using the difference algorithm 148 of the dispatch server 126) each current image 144 of an interior cavity 402 with the corresponding baseline image 122 of a cargo cavity. The processor 118 associated with the sensor array 106 is configured to determine a cargo status 124 (e.g., using the cargo status algorithm 125 of the dispatch server 126) based upon a difference 148 (e.g., using the difference algorithm 148 of the dispatch server 126) between the current image 144 and the baseline image 122. Furthermore, the processor 118 is configured to send the cargo status 124 to a dispatcher 134 using a cellular modem 136.

In yet another embodiment, a trailer 102 of a semi-trailer truck 104 includes a sensor array 106 affixed to a surface 108 of the trailer 102 to automatically determine whether a cargo area 110 of the semi-trailer truck 104 is occupied. The trailer 102 of the semi-trailer truck 104 also includes a set of cameras 112 of the sensor array 106. Each camera of the set of cameras 112 is each embedded in individual recess(es) 113 of the sensor array 106 such that each of the set of cameras 112 are interior to a flush plane of the surface 108 to prevent cargo from damaging each camera.

The trailer 102 of the semi-trailer truck 104 further includes at least one light source 114 to illuminate the cargo area 110.

A memory 116 and a processor 118 associated with the sensor array 106 are configured to store one baseline image 122 of the cargo area 110 of the trailer 102 when the trailer 102 is in an empty state. The processor 118 is configured to detect a triggering event 206 and/or to illuminate the cargo area 110 of the trailer 102 using at least one light source 114. The processor 118 is further configured to capture a current image 144 of the cargo area 110 of the trailer 102 using the set of cameras 112. The processor 118 is also configured to compare each current image 144 of an interior cavity 402 with the corresponding baseline image 122 of a cargo cavity. Furthermore, the processor 118 is configured to determine a cargo status 124 (e.g., using the cargo status algorithm 125 of the dispatch server 126) based upon a difference 148 (e.g., using the difference algorithm 148 of the dispatch server 126) between the current image 144 and the baseline image 122. Also, the processor 118 is configured to send the cargo status 124 to a dispatcher 134 using a cellular modem 136.

The sensor array 106 includes a backup camera 202 to observe a rear area 204 of the trailer 102 of the semi-trailer truck 104. The backup camera 202 is mounted to the sensor array 106 such that the backup camera 202 views (e.g., using the triggering event algorithm 142 of the dispatch server 126) a door of the trailer, a loading area of the trailer, and/or an area behind the trailer. A driver 208 of the trailer 102 may view a video feed 210 from the backup camera 202 using a wired connection and/or a wireless connection between the backup camera 202 and/or a display 212 in a cabin area 214 of the semi-trailer truck 104.

Particularly, FIG. 1A illustrates the trailer 102, a network 101, the semi-trailer truck 104, the sensor array 106, the surface 108, the cargo area 110, a set of cameras 112, a recess 113, a light source 114, a projection areas 115, a memory 116, a processor 118, a database 120, a baseline image 122, a cargo status 124, a cargo status algorithm 125, a dispatch server 126, a dispatch server memory 128, a dispatch server processor 130, a dispatch server database 132, a dispatcher 134, a user device 135, and a cellular modem 136, according to one embodiment.

The trailer 102 may be a nonmotorized vehicle designed to be hauled by a motor vehicle (e.g., a truck, utility vehicles, and/or a tractor). The network 101 may be a group of computing devices (e.g., hardware and software) that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of entities (e.g., dispatcher 134). The semi-trailer truck 104 may be a large vehicle that consists of a towing engine, known as a tractor and/or a truck, attached to one or more semi-trailers to carry freight, according to one embodiment.

The sensor array 106 may be a device in the form of a bar and/or a series of bars that may be affixed to a wall and/or upright supports (e.g., a surface 108 of the trailer 102) which detects or measures a physical property (e.g., light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena) of the occupancy inside the trailer 102 and records, indicates, and/or otherwise responds to it as an output. The sensor array 106 (e.g., a sensor rail, a sensor housing, etc.) may hold a single camera or may hold multiple cameras. The sensor array 106 may be connected through a wired and/or wired networking topology. In one embodiment, cameras are positioned in different locations of the trailer 102 individually, and the sensor array 106 provides a housing in which to communicatively couple the sensor array 106 to the trailer without the need of a separate rail. In another embodiment, the sensor array 106 includes multiple cameras on a single sensor rail. The sensor array 106 may include optional temperature, humidity, and/or pressure sensing in addition to visual sensing to determine general conditions in which cargo is housed inside the trailer 102.

The output may be generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over the network 101 for reading or further processing to determine the cargo status 124 of the trailer 102. The surface 108 may be the uppermost layer of the wall or ceiling of the trailer 102 on which the sensor array 106 is affixed.

The processor 118 may be a logic circuitry that responds to and processes the basic instructions that drives the sensor array 106 for monitoring the semi-trailer truck 104. The database 120 may be a structured collection of information collected by the set of cameras 112 that is organized to be easily accessed, managed, and/or updated by the dispatcher 134. The baseline image 122 may be a visual representation of the inside of the cargo area 110 of the trailer 102 at an empty state. The cargo status 124 may be the present situation of the cargo area 110 in terms of occupancy of goods in the trailer 102 as captured by the set of cameras 112. The cargo status algorithm 125 may be a process or set of rules to be followed in calculations or other problem-solving operations for identifying the occupancy of goods in the cargo area 110 of the trailer 102.

The dispatch server 126 may be a computer system that provides local area networking services to multiple users (e.g., dispatcher 134) to send off the cargo to its respective destination by managing resources and services of the network 101, while handling requests by the dispatcher 134 from different computers to access the said resources, according to one embodiment.

Particularly, FIG. 1B illustrates a separate housing 138, an exterior face 140, a triggering event algorithm 142, a current image 144, a composite view 146, and a difference algorithm 148, according to one embodiment.

According to at least one embodiment, the separate housing 138 may be a discrete rigid casing that encloses and protects the various components of the sensor array 106. The exterior face 140 may be outermost part of the middle-top section of the trailer 102 on which the sensor array 106 is affixed. The triggering event algorithm 142 may be a process or set of rules to be followed in calculations or other problem-solving operations for identifying the occurrence of a trailer opening event, a trailer closing event, a motion detection event (e.g., using a global positioning device and/or a motion sensor), a stopping event, a time-based event, a geographic-location based event, and/or a velocity based event of the trailer 102 of semi-trailer truck 104, according to one embodiment.

The current image 144 may be the present visual representation of the inside of the cargo area 110 of the trailer 102 after occurrence of the triggering event. The composite view 146 may be a combined visual representation of the inside of the cargo area 110 of the trailer 102 captured by the set of cameras 112 after occurrence of the triggering event. The difference algorithm 148 may be a process or set of rules to be followed in calculations or other problem-solving operations for identifying the distinctness or dissimilarity of the composite view 146 of the cargo area 110 after occurrence of the triggering event from the baseline image 122 of the cargo area 110 at an empty state, according to one embodiment.

FIG. 1B illustrates a sensor array 106 affixed to a middle-top section of the trailer 102 on the exterior face 140. The sensor array 106 is placed in a separate housing 138 from the cargo area, according to one embodiment.

The cargo status 124 based on a triggering event may be automatically determined using the sensor array 106. In circle ‘6’, a triggering event (e.g., using the triggering event algorithm 142 of the dispatch server 126) is identified by the processor 118 of the sensor array 106. In circle ‘7’, a current image 144 captured by the set of cameras 112 is communicated to the dispatch server 126. In circle ‘8’, the composite view is communicated to the dispatch server 126.

A current image 144 is captured by each of the set of cameras 112. A composite view 146 is generated based on the current image 144 captured by each of the set of cameras 112. The composite view 146 and the baseline image 122 is compared to conclude the cargo status 124 (e.g., using the cargo status algorithm 125 of the dispatch server 126) of the trailer 102. The cargo status 124 is communicated to the dispatcher 134, according to one embodiment.

FIG. 4 is a composite view 450 illustrating the overlapping distortion 406 captured by each camera 112A-D of the set of cameras 112 of the sensor array 106 of FIG. 1 providing the cargo status 124 of the trailer 102, according to one embodiment.

The interior cavity 402 may be an empty space inside the trailer 102 of the semi-trailer truck where the cargo is kept for dispatch. The field of view 404 may be the extent or measurement covered by each camera of the set of cameras 112 to capture visual images of the inside of the trailer 102 in the form of photographs, film, or video signals. The overlapping distortion 406 may be the covering or extension of field of view 404 of one camera over the field of view 404 of its adjoining camera of the set of cameras 112 of the sensor array 106, according to one embodiment.

Particularly, composite view 450 illustrates an example embodiment of the sensor array 106 running the length of the trailer 102 with embedded set of cameras 112, electronics, wiring and LED light source and other sensors mounted on ceiling. Each camera is looking for distortion from reference baseline image 122. No distortion from any of the camera indicates that the trailer is empty. Overlapping distortion 406 provides information on the extent of quadrant load in each of the projection areas 114A-E. Each quadrant (e.g., projection areas 114A-E) represents 20% of the cargo area 110. If only projection area 114A has distortion, then the trailer </=20% full. If projection areas 114A and B has distortion, then the trailer </=40% full. If only projection areas 114A, B and C has distortion, then the trailer </=60% full and if projection area 114A, B, and C has distortion, then the trailer is </=80% full, according to one embodiment.

FIG. 5 is a table view illustrating the storing of undistorted baseline image 122 captured at empty state of the trailer 102 of FIG. 1 and the corresponding distorted image after occurrence of the triggering event 206 for determining the cargo status 124, according to one embodiment.

Particularly, FIG. 5 illustrates an example of two records for a dispatcher 134 with two trailers having a sensor array having a set of cameras 112 affixed to each of its trailer 102. The baseline image(s) 122 captured in empty state of the trailer 1 and 2 shows no distortion as shown in the 502 field. The triggering event 206 caused by the trailer opening event in trailer 1 depicts a distortion in current image 504 captured by camera 112A of trailer 1. The resulting cargo status 124 is shown as </=20% full caused by the triggering event 206 as communicated to the dispatcher 134. Similarly, the triggering event 206 caused by the velocity based event in trailer 2 depicts a distortion in current image 504 captured by camera 112A-C of trailer 2. The resulting cargo status 124 is shown as </=60% full caused by the triggering event 206 is communicated to the dispatcher 134, according to one embodiment.

An example embodiment will now be described. The ACME Haulage Corporation may provide cargo transportation services in remote areas of the United States. The ACME Haulage Corporation may be compensated based on a type of goods being carried inside a cargo area of its trailer of a transportation vehicle (e.g., a semi-trailer truck 104). For this reason, the ACME Haulage Corporation may want to understand the ‘load’ status of their equipment (e.g., a semi-trailer truck 104) to optimize the dispatch and routing of their transportation assets. In order to understand the load status of their equipment (e.g., a trailer 102), the ACME Haulage Corporation may have to rely on field reports. The ACME Haulage Corporation may have employed sensors (e.g. weight sensors, wave sensors, ultrasound sensors) in an interior space of its trailers. These sensors may not be able to detect patterns or types of cargo and exactly where in the trailer the cargo is located. The incorrect and unreliable cargo status provided by these sensors may have resulted into a number of untoward situations. For example, a driver of its semi-trailer truck may have embarked on a long journey, when, in fact, its cargo area is filled with the wrong type of cargo or may even be empty. This may have lead The ACME Haulage Corporation to a loss of invaluable time, fuel, efficiency, customer dissatisfaction, and/or ultimately, loss of revenue for its services.

To prevent these continuing losses, the ACME Haulage Corporation may have decided to invest in embodiments described herein (e.g., use of various embodiments of the FIGS. 1-9) for optimum utilization of interior spaces of the cargo area of its trailers (e.g., a trailer 102). The use of technologies described in various embodiments of the FIGS. 1-9 may enable the dispatch managers of ACME Haulage Corporation to remotely monitor and manage its entire fleets of cargo transport equipment (e.g., trailer 102) and asset utilization in real-time. The various embodiments of the FIGS. 1-9 may have also enabled the dispatch managers of the ACME Haulage Corporation to know the actual load status of its cargo transport equipment (e.g., a trailer 102) through image analysis and to verify the contents of the equipment through a photographic image. Additionally, the image analysis may have enabled the central dispatch (e.g., dispatcher 134) of the ACME Haulage Corporation to know what areas and/or zones of the equipment (e.g., trailer 102) are actually loaded.

The use of technologies described in various embodiments of the FIGS. 1-9 facilitated the dispatch managers (e.g., dispatcher 134) of ACME Haulage Corporation to utilize an easy-to-use mobile interface, giving it real-time visibility of the cargo areas of its trailers for their daily operations along with helping dispatch managers (e.g., dispatcher 134). The dispatch managers (e.g., dispatcher 134) of the ACME Haulage Corporation may now be able to automate manual business processes and optimize performance of its transportation equipments (e.g., trailer 102) by using the rich data platform as described in various embodiments of the FIGS. 1-9 maximizing trailer utilization.

The use of technologies described in various embodiments of the FIGS. 1-9 may have enabled trailer management system of the ACME Haulage Corporation to instantly connect dispatch managers to a host of powerful, easy-to-use analytics and insights via web-based, highly intuitive trailer tracking dashboards, customizable trailer tracking reports and exception-based alerts. Armed with this intelligence, dispatch managers (e.g., dispatcher 134) of the ACME Haulage Corporation may have the ability to automate yard checks; better manage and distribute trailer pools; improve detention billing; increase the efficiencies and productivity of dispatch operations; secure trailers and high-value cargo; deter fraud and unauthorized trailer use; improve driver and customer satisfaction; and maximize trailer utilization for a more profitable fleet. The ACME Haulage Corporation may now utilize their cargo area to its optimum capacity. This may have lead the ACME Haulage Corporation to save time, fuel, increase efficiency, customer satisfaction, and/or ultimately, prevent loss of revenue for its transportation services raising its profit.
